Using Whole-of-Life Insurance to Pay Inheritance Tax

By CareFinder Team · Published 2026-07-17 · Last reviewed 2026-09-18

Whole-of-life insurance pays a lump sum whenever you die, so it can give your family money to pay an inheritance tax bill. For it to help, the policy usually needs to be written in trust: a policy you own on your own life pays into your estate and can itself be taxed. Premiums are gifts too, although regular premiums paid from surplus income are often exempt.

Whole-of-life insurance pays out whenever you die, as long as the premiums are kept up. That makes it one way to give your family a lump sum to pay an inheritance tax bill, so they do not have to sell a house or investments in a hurry. It does not reduce the tax itself, and it only works well if the policy is set up correctly, usually in trust.

This guide covers inheritance tax, which applies across the UK. It is general information; talk to a regulated financial adviser and a solicitor before buying a policy or setting up a trust.

How big could the inheritance tax bill be?

Inheritance tax is charged at 40% on the part of an estate above the tax-free threshold, according to GOV.UK. The main points:

• The nil-rate band is £325,000 per person.
• The threshold can rise when a home is left to children or grandchildren, through the residence nil-rate band, for estates worth less than £2 million.
• Anything left to a spouse or civil partner is normally free of inheritance tax, and any unused threshold can pass to the survivor.
• The rate falls to 36% on some assets if 10% or more of the net estate goes to charity.

The government has fixed these thresholds until April 2031, as announced at Budget 2025. The same announcements confirmed that, from 6 April 2027, most unused pension funds and death benefits will be counted in the estate. That change could increase some families' bills.

Before looking at insurance, it is worth estimating the likely bill with a professional: the answer might be less than you fear, or more.

How does whole-of-life insurance work?

• You pay premiums, monthly or yearly, for the rest of your life, or until an age set in the policy.
• The insurer pays a fixed sum when you die, whenever that is.
• If you stop paying, cover usually ends and you may get nothing back.

There are different kinds:

• Guaranteed premium policies fix the premium for life.
• Reviewable premium policies can have premiums raised after reviews, sometimes sharply in later life.
• Joint life, second death policies cover a couple and pay out when the second person dies. This is often when inheritance tax becomes due, because assets left to a spouse are usually exempt.

Term insurance, by contrast, only pays if you die within a fixed period, so it is rarely suitable for an inheritance tax bill that could arise at any age.

Why does writing the policy in trust matter?

If you own a policy on your own life, HMRC treats the payout as part of your estate. That means the money meant to pay the tax could itself be taxed at 40%.

Writing the policy in trust changes this. The policy is held by trustees for the people you choose, so the payout goes to them rather than into your estate. Insurers usually provide trust forms. Other benefits:

• the trustees can usually claim the money without waiting for probate, so it can be available when the tax is due;
• you choose who the trustees and beneficiaries are.

Trusts have their own inheritance tax rules, and the wrong type of trust can cause problems. Take advice on which trust suits the policy.

Are the premiums gifts?

Yes, when you pay premiums on a policy held for someone else's benefit. HMRC's manual says premiums can be treated as gifts, subject to any exemption. In practice, premiums are often covered by:

• the annual exemption of £3,000 of gifts each tax year; or
• the exemption for normal expenditure out of income, which has no upper limit if the payments are regular, come from income rather than savings, and leave you enough to maintain your usual standard of living.

The GOV.UK gifts guide explains both. Keep records of your income and spending, as your executors may need to show the premiums were exempt.

When is inheritance tax due?

Inheritance tax must usually be paid by the end of the sixth month after the death, and interest is charged after that. GOV.UK says some tax usually has to be paid before the executors get probate. Tax on property can often be paid in yearly instalments. A policy in trust can provide cash quickly, helping to avoid a forced sale.

Is it worth it?

It depends on age, health, the size of the likely bill and how long you live. Things to weigh:

• Cost. Premiums rise with age and ill health. Over a long life, total premiums can exceed the payout.
• Affordability. Paying premiums must not put your own care or living costs at risk.
• Alternatives. Gifting during your lifetime, spending, leaving money to charity or using reliefs may reduce the bill directly.
• Care costs. If you might need to pay for care, keep enough accessible money.

Over-50s plans sold for funeral costs usually pay much smaller sums and are not designed for inheritance tax.

How do you set it up?

1. Get an estimate of the likely inheritance tax bill.
2. Speak to an FCA-regulated independent financial adviser about suitable policies.
3. Compare guaranteed and reviewable premiums, and single-life and joint-life cover.
4. Write the policy in trust from the start, with advice on the right trust.
5. Pay premiums from income if you want to use the normal expenditure exemption, and keep records.
6. Tell your executors and trustees where the documents are.

Frequently asked questions

Is the payout from a life insurance policy tax-free?

Life insurance payouts do not attract income tax, but if you own the policy on your own life, the payout is part of your estate for inheritance tax. Writing it in trust usually keeps it outside the estate.

What is a joint life, second death policy?

It covers a couple and pays out when the second person dies. Because assets passing to a spouse or civil partner are usually exempt, the bill often falls on the second death, which is when this cover pays.

Can I put an existing policy into trust?

Often yes, and insurers can supply forms. Transferring an existing policy may count as a gift of its value, so take advice first.

Does life insurance reduce inheritance tax?

No. It provides money to pay the tax. Reducing the tax itself involves gifts, exemptions, reliefs, charitable giving or spending.

What happens if I stop paying premiums?

With most whole-of-life policies, cover ends and you may receive little or nothing back. Check whether premiums are guaranteed or reviewable before buying.

• Premiums are gifts, often covered by the annual or normal-expenditure exemption.
• Inheritance tax thresholds are fixed until April 2031, and pensions join estates from April 2027.
• Compare the total cost of premiums with other ways to plan, and take regulated advice.
